Castor oil is an effective motor lubricant and has been used in [[internal combustion engine]]s, including those of [[World War I]] airplanes, some racing cars and some [[model airplanes]]. It has historically been popular for lubricating [[two-stroke engines]] due to high resistance to heat compared to petroleum-based oils. It does not mix well with petroleum products, particularly at low temperatures, but mixes better with the methanol-based fuels used in [[Glow plug (model engine)|glow model engines]]. In [[Total-loss oiling system|total-loss-lubrication]] applications, it tends to leave carbon deposits and varnish within the engine. It has been largely replaced by synthetic oils that are more stable and less toxic.
